If you've heard all about 4K video but you aren't sure what it is and whether or not it matters to you, this two-minute video primer from the folks at Mashable will get you up to speed quickly.

Now that 4K monitors are starting to hit store shelves and everyone's talking about 4K television, the question remains whether it'll be a fad that stays too expensive for consumers with no content to back it up, or it'll be the next thing to sweep at-home video and computer workstations. Time will tell, but if you're not familiar with 4K, this video explains that 4K—at least in terms of home entertainment—has everything to do with the number of vertical lines in the resolution of an image. What that really means to you is that 4K video has roughly twice the resolution of standard 1080p HDTV, or that you could fix four 1080p HD images inside of one 4K image, pixel-wise.

4K video isn't without its drawbacks though. The video goes onto explain that current 4K video streams are so data heavy, even from directly-connected sources like camcorders and media players—that connection technologies have to catch up to properly push that data, otherwise they'll be a bottleneck, especially when it comes to streaming over the internet. They also talk about some of the sharpness and color drawbacks from having such incredible pixel density on modestly sized displays.
